ZigBee is a low power consumption local area network protocol based on IEEE802.15.4 standard. According to international standards, the ZigBee technology is a short-range, low-power consumption wireless communication technology. The ZigBee protocol is, from bottom to top, a physical layer (PHY), a media access control layer (MAC), a Transport Layer (TL), a network layer (NWK), an application layer (APL), and the like. Wherein the physical layer and the medium access control layer comply with the provisions of the IEEE802.15.4 standard. The underlying technology of ZigBee is based on IEEE802.15.4, i.e. its physical layer and medium access control layer directly use the definitions of IEEE 802.15.4.
The ZigBee network has the main characteristics of low power consumption, low cost, low speed, support of a large number of nodes, support of various network topologies, low complexity, rapidness, reliability and safety. Devices in the ZigBee network can be divided into three roles, namely, a Coordinator (Coordinator), a sink node (Router), and a sensor node (end device). Meanwhile, as a short-distance wireless communication technology, the ZigBee network can conveniently provide a wireless data transmission function for users.
The Mesh topology (Mesh topology) comprises a Co-coordinator and a series of routers and End devices. This network topology is the same as the tree topology. However, mesh network topologies have more flexible information routing rules, and routing nodes can communicate directly with each other, where possible. This routing mechanism makes the communication of information more efficient and means that once a problem occurs on one routing path, the information can be automatically transmitted along the other routing path.
The intelligent lockset realizes a real-time online function based on a 2.4GHz ZigBee wireless network. The first base station gateway and the intelligent lock are self-organized through a Mesh topology network based on 2.4GHz ZigBee, and the intelligent lock data are forwarded to the intelligent anti-error background through the first base station gateway; similarly, the data of the intelligent anti-misoperation background is forwarded to the intelligent lockset through the first base station gateway.
In an intelligent lock ZigBee Mesh network, a first base station gateway is used as a coordinator Co-coordinator, an intelligent lock is used as a terminal Device End Device, and a series of network relays are added in a network system to serve as a Router; in the network system, the communication data is encrypted by AES 128.
The ZigBee communication unit of the network relay completes searching connection and data forwarding work of the network, when the network relay detects a network signal established by the coordinator, the network relay can be automatically connected, and after the network relay is successfully connected, the ZigBee communication unit sends state information such as an MAC address of the first base station gateway.
The ZigBee communication unit of the intelligent lock completes searching connection and data receiving and sending work of a network, when the intelligent lock detects a network signal established by a coordinator or a network relay, the intelligent lock can be automatically connected, state information such as an MAC (media access control) address of the intelligent lock is sent to the first base station gateway after the intelligent lock is successfully connected, and the first base station gateway receives the data sent by the intelligent lock and forwards the data to the intelligent anti-misoperation background.
When data interaction is carried out between the intelligent anti-misoperation background and the intelligent lock through the first base station gateway, distinguishing and forwarding are realized based on the MAC address of the intelligent lock.
